Five companies operating dockless bikes and motorized scooters in the District remain as Ofo and Mobike exit the market. Jump and Spin operate only bikes. The companies Waybots and Bird have electric scooters. Limebike has both types of vehicles.

Some neighbors have seen the bikes, which sometimes get left in strange or obtrusive locations, as a nuisance. But others have seen them as a way to fill gaps where there is limited access to Capital Bikeshare docking stations.

In response to the news, the District Department of Transportation released a statement saying that Mayor Muriel Bowser is still focused on safe, reliable and affordable transportation.

"We appreciate the participation of all the companies and look forward to using the information collected during the demonstration project to arrive at long-term options for the use of dockless vehicles in the District," the statement said.

Mobike has started giving customers refunds. They said they began removing the bikes from D.C. streets and expect to have most removed by next week.
